Ah ha,
The old to saddle soap or not to saddle soap debate rises again.
I have used saddle soap along with other products for may years and have had no problem with it.
Just as many recommend it's use as those like Judy from LTT ( a supplier of leather cleaning products
sorry Judy couldn't resist it) who don't.
I know the all the arguments against, finish removal, attracts oils etc etc but I have used other products some good some not so good and have always ,especially on British made leather products, gone back to using saddle soap.Why British? the reason I have found is that imported leather is usually such poor quality, heavily treated to hide blemishes which are perfectly natural and should be left alone, that applying any thing other than fresh air can cause a problem, hence foam cleaners.
Indeed I deal with one British Manufacturer of fine leather furniture who RECOMMEND that their furniture should be washed using a cloth soaked in soapy water and then rinsed with cold water.
How many of us would do that? not many I suspect.
I understand where you are coming from Judy in the better safe than sorry statements but dismissing it's use out of hand in my opinion is wrong.
After all the Ecclesiastical Society and C of E will only allow the use of saddle soap on leather in Churches if it's good enough for them then it's good enough for me.
